SARATOGA SPRINGS, N.Y. – Former Massachusetts Gov. William Weld, campaigning for the GOP nomination for New York governor, blasted Eliot Spitzer yesterday for using “terror power” to gain a reputation as the top prosecutor of Wall Street abuses.

An aide to state Attorney General Spitzer, the likely Democratic gubernatorial nominee, responded: “Mr. Weld is a stranger to New York and he doesn’t know what he’s talking about when it comes to Eliot’s record.”

At an appearance at the Saratoga race track, Weld said Spitzer “has a marvelous public persona.”

But Weld, a former federal prosecutor and top U.S. Justice Department official, contended Spitzer’s popularity was “based 100 percent on terror power, which is the power of ruination . . . for whoever the subject of the indictment or charge is.”
